I need help getting various ARDUINOs to accept an upload to perform the basic "Blink" test.
What is happening? When I try to upload the two lines of Blink, the board manager screen flashes then stops. USB's drop out and ping with the sound they drop out twice during the sketch upload of the simple Blink program with board and com port configured. Happens on Windows 10 PC and laptop, with Arduino UNO and 101 boards, and with two separate cables, and with and without battery pack powering boards
